6 Claims.

This invention relates to a tying fixture. One of the objects of the invention is to provide a tying fixture.

Another object of the invention is to provide a tying fixture provided with tie string loop spacing and supporting means.

. Other objects of the invention will be apparent from the description and claims which follow.

By way of illustration but without limitation, the fixture of the present invention is exemplied for'use in tying wrapped whole hams, bacon slabs, and products of a similar character. It may be used for tying boxes, cartons, and other articles of various types and shapes.

The invention contemplates the use of a pair of tie string loop spacing and supporting means mounted relative to' a product supporting means. In accordance with the invention, a pair of slip knots providing loops are spacedly formed in a length of string. The formed loops are passed over the ends and around the body of the article `to be tied and are drawn tight at the knots by pulling on the loose ends of the string. The ends of the string are then drawn over the ends of the 25 article, following which the article is turned over on its opposite side and tying is completed in the usual manner.

In the drawings, like characters of reference are used to designate .similar parts.

Figure 1 is a perspective view of a tying fixture constructed in accordance with the present invention.

Figure 2 is a plan view of the device shown in Figure 1, the article supporting means being removed.

Figure 3 is a plan view, showing one of the knot spacing and supporting means.

Figure 4 is a side view of Figure 3.

Figure 5 is a plan view showing one supporto ing surface of the article supporting means.

Figure 6 is an end view of Figure 5.

Figure 7 is a side view of Figure 5.

Figure 8 is a fragmentary view illustrating one of the steps in the formation of the spaced knots and tying loops.

Figure 9 is a fragmentary view illustrating another of the steps in the formation of the knots and tying loops.

Figure 10 is a front view of the device, showing the final step in the formation of the knots and tying loops. Also, in this figure is illustrated the opposite face of the article supporting means and the looped string being secured about a wrapped slab.

The device of the present invention comprises a base plate i provided with a forward retaining ledge 2, rear wall 3, and a, plurality of openings I, for securing the same to a table or other suitable supporting means.

Saddle block 5 is provided with reversible article supporting surfaces 6 and 1 and is made to fit upon base I between ledge 2 and rear wall 3. In the device exemplified in the drawings surface 6 of block 5 is gouged in a particular manner for more suitably supporting an article of irregular configuration such as a ham or the like. Surface 'I may be made at for supporting articles of substantially rectangular configuration such as bacon slabs and the like. It will be understood that surface 6 may be gouged in a manner different to that shown in the drawings for suitably supporting articles of other configuration. It also will be understood that surfaces 6 and 'I may both be gouged to support articles of different types. It further will be understood that if it is desired to tie only articles of one conguration, block 5 may be provided with a single surface in which case, block 5 may be formed integral with base I.

Plate 8 is xedly secured as by screws 9 to the forward end of block 5 and serves as a retaining ledge when the fiat surface 'lis brought into use. When it is desired to use surface 6, ledge 8 is tted through slot I0 in base plate I in the manner shown in Figure 1.

Block 5 as is more clearly shown in Figure 6 may be grooved, as at I I, at each of its side edges, thus providing bevelled edges I2 and I 3 approaching surfaces 6 and 1, respectively. Bevelled edges I2 and I3, each serve as an aid to properly locate the loops about the article being tied in a manner hereinafter described.

T bracket I4 comprising vertical member I5 and horizontal ledge I6 is fixedly secured to rear wall 3, as by bolts I l, passed through openings provided in Wall 3 and slots I8. It will be noted that slots I8 provide for adJustment of ledge I8 relative to block 5.

In the device of the present invention a pair of loop spacing and supporting rods I9 are adjustably horizontally secured on ledge I6, as by claw clamps 20, and screws 2|. Rods I9 may be formed integral with clamps 20. Rods I9 preferably are slightly curved downwardly to facilitate removal of the formed knots and may be provided at their fixed ends 22 with shields 23 for preventing entanglement of string 24 with the clamp and ledge mechanism.

In use the article is placed upon block 5 and is approximately centered between the side edges thereof.

A group oi' lengths of string used for tying may be previously formed or if desired may be sep` arately formed by pulling and cutting from a. ball of string in the conventional manner, not shown. For this latter purpose cutter 25 may be conveniently secured on one of the clamps 20.

As shown in Figures 8, 9, and 10 the length of string is gripped by an operator, not shown, with each hand at points spaced approximately from its center, and by movements of the lingers of both hands the operator forms two loose slip knots 21 and loops 25 at the gripped points.

The operator then throws the loops 26 over the rods I9 in the manner shown in Figure 9 and by an outward movement of the two hands draws the knots 21 fairly tight at the points of contact with rods I9. The operator while still maintaining a hold on the loops releases the loops from rods I9 and places the same around the article to be tied with the lateral length of string 28 between knots 21 on top of the article in the manner shown in Figure 10. The operator then grips the free ends 29 of the string and draws the loops tightly around the package. 'I'he operator while still holding the ends of the string seizes the ends of the article and flips it over on its opposite side. At this point the ends of the string may be severed to their correct length for tying by use of the cutter 25. The free ends of the string are then passed over and under their respective loopl string after which the two ends are joined in a nal knot.

It will be seen that rods I9 serve to space the two knots Within the length of string. Also, according to the article being tied rods I9 may be suitably spaced on ledge I6 to provide an appropriate length of lateral string 28 between the knots 21.

It wm further be seen that the grooves n in' block serve to facilitate placement of the loops about the article adjacent the side edges of the block 5 which by reason of the article being approximately centered on the block 5 will equally space the loops from the ends of the tied article.

I claim:

1. Means for spacing and supporting a pair oi' tie loops in a tie string comprising a pair of spaced substantially parallel rods and means ad- Justably mounting one of said rods for sidewise movement from and toward the other of said rods.

2. Means for spacing and supporting a pair oi' tie loops in a tie string comprising a vpair of spaced, substantially parallel rods, each flxedly secured at one of its ends to a supporting clamp and means adJustably mounting said clamp whereby said rods may be secured in substantially parallel relation with each other in any one of a plurality of adjusted positions.

3. Means for spacing and supporting a pair oi' tie loops in a tie string comprising a pair of spaced, substantially parallel rods, each xedly secured at one of its ends to a supporting clamp and means adjustably mounting said clamp whereby said rods may be secured in substantially parallel relation with each other in any one of a plurality of adjusted positions, and a shield provided at the xed end of each of said rods.

4. Means for spacing and supporting a pair of tie loops in a tie string comprising a pair of spaced rods and means adjustably mounting one of the rods for movement from and toward the other of the rods while maintaining the same f geometrical relation to the other of the rods. y

5. A tying device comprising a product supporting base, an upright secured in functional relationship with the base and means including a pair of spaced rods extending from the upright and above the base for supporting and spacing a pair of tie loops in a tie string to facilitate tying an article supported on the base.

6. A tying device comprising a base, an upright mounted on the base, spaced loop supporting and spacing rods secured to the upright and extending in substantially parallel relationship above the base, the base being so positioned relative to the parallel rods that an article placed thereon will be in such proximity to the rods to facilitate passage around the article of a string with loops of the string about the rods in tie formation thereon.
